Description
Technical field
The value-added service that the present invention relates in a kind of digital television devices is handled, and specifically, relates to a kind of implementation method of quickly switching to value added service of digital television, belongs to the digital television techniques field.
Background technology
Along with the continuous development of digital television techniques, value added service of digital television has become an important content of present Digital Television development, also is the key technology means in each big businessman contention Digital Television market.The value-added service that present Digital Television provides can be divided into digital television broadcasting and digital television interaction two big classes according to the difference of service function; Digital television interaction can divide be as the criterion digital television interaction and two-way interaction Digital Television again.Digital television broadcasting provides the digital television program of high-quality, single-definition, comprises quasi-video request program, accurate Audio on Demand, stereo music channel and encrypts paying digital television business etc.Accurate digital television interaction mainly is meant data broadcasting, adopts the data message broadcast technology to realize with interactive application software, pushes information to the user side set-top box with the interface form of expression that both pictures and texts are excellent and receives.This class value-added service comprises multimedia magazines such as news information, lottery information, also comprises information consultations such as real-time stock market information, weather information etc.The two-way interaction Digital Television then is by increase bi-directional communication device on technology platform, utilize the set-top box realization information interaction truly of built-in Cable Modem or network interface card, realize such as business such as TV online, TV Mail, long-distance education, Home Bankings.
In digital television devices such as the existing digital TV set-top box that value-added service is set, digital television, owing to all need to create running example when entering value-added service at every turn, related resources such as load page and picture, literal, animation, therefore, the value-added service admission velocity is slower, causes in the digital television devices switch speed between the value-added service function and Digital Television basic function slower.
For the admission velocity that improves value-added service, to accelerate to switch to the speed of value-added service, prior art can adopt two kinds of solutions: a kind of method is to reduce the interface data amount, and another kind of method is not use value-added service and use middleware instead.
For first method, reducing interface data amount itself can only be as a kind of method of local optimum speed, this be because: on the one hand, along with popularizing of high-definition digital signal, the increase of value-added service data volume is inevitable; On the other hand, when entering value-added service, though data volume has reduced, the time of creating running example and resource bid still exists.
For second method, if the middleware that uses other functions with value-added service and Digital Television to integrate, set-top box manufacturer need carry out software development again to set-top box or Digital Television, integrated, authentication and test middleware and other value-added functionalitys, original investment can't be protected, and the construction cycle is longer relatively; The radio and TV operator then needs to change calculator room equipment, abandons original increment service system, purchases new middleware system again, and the original system that has come into operation will form huge waste.

A1, judge whether value-added service is in resting state;
A2, when value-added service is resting state, wake value-added service up; When value-added service is non-resting state, create the value-added service example;
A3, execution value-added service;
In withdrawing from the process of value-added service, comprise that value-added service is set to resting state, resides in the step in the internal memory.
According to the present invention, the detailed process that value-added service is set to resting state is: the current screen of value-added service is saved in the internal memory; Remove current screen then; The state variable value that value-added service is set again is the resting state value.
The detailed process of waking value-added service up is: the current screen of the value-added service of storing in the recovery internal memory; The state variable value of value-added service is set to the running status value then.
According to the present invention, in described step a1, can judge whether value-added service is in resting state according to described state variable value.
According to the present invention, in resting state, value-added service stops to receive the value-added service data resource, continues the system message of receiving digital television, but value-added service main task module only handles and wake relevant system message up, and does not handle other system message.
According to the present invention, carry out in the process of value-added service at described step a3, also comprise the deterministic process that judges whether to withdraw from value-added service.When value-added service is withdrawed from judgement, carry out the process that withdraws from value-added service; If need not withdraw from, then continue to carry out the value-added service process.
According to the present invention, described process and the described process that withdraws from value-added service of waking value-added service up triggers by external event.
Compared with prior art, advantage of the present invention and good effect are: the present invention is by being provided with dormancy mechanism and arouse machine processed for value added service of digital television, when value-added service is withdrawed from, by dormancy mechanism value-added service is resided in the internal memory, and do not influence other functions of digital television devices; When carrying out value-added service once more, from internal memory, directly recover the last time page at the value-added service place of resting state storage by arouse machine processed, and be presented on the screen, and do not need to create again the value-added service application example, load respective resources, improved the admission velocity of value-added service, realize the moment switching between value-added service function and the Digital Television basic function, improved the overall performance of digital television devices.

S205:, show after digital TV set-top box starts and carried out the function of data broadcasting, and data broadcasting has been resided in the internal memory if data broadcasting is in resting state.At this moment, only need directly wake data broadcasting up from internal memory gets final product.And then execution in step S206.
When waking data broadcasting up, at first recover the current screen of the data broadcasting stored in the internal memory; The state variable value of data broadcasting is set to the running status value then.The current screen of described data broadcasting is meant the screen of being preserved when last time data broadcasting carried out resting state.
S206: the corresponding data resource that receives data broadcasting.
S207: whether judgment data broadcasting is in resting state.If be in resting state, go to step S206, continue to receive data resource; If non-resting state, then execution in step S208.
The meaning that this step is set is, if the data broadcasting function is the function of current execution, then data broadcasting will continue the corresponding data resource of receiving system message and data broadcasting, and need handle accordingly the data resource that receives, to realize the function of data broadcasting; If data broadcasting is in resting state, at this moment, data broadcasting main task module is still in operation, still can receiving system message, but do not handle, be waken up up to data broadcasting, when changing running status into, just continue receiving processing system message by resting state.And, under resting state, also will stop to receive the data resource of data broadcasting.
S208: when data broadcasting is non-resting state, judge whether to withdraw from data broadcasting.If will withdraw from data broadcasting, execution in step S210; If do not withdraw from, execution in step S209 then.
S209: at data broadcasting is non-resting state and when not moving back, and handles the data resource that the main task module receives, and carries out the data broadcast capability.
S210: if will withdraw from data broadcasting, it is resting state that data broadcasting then is set, and goes to step S206 then, continues to receive data resource.
The process that data broadcasting is set is resting state is: at first the current screen with data broadcasting is saved to the space of reserving for data broadcasting in the internal memory; Remove current screen then, so that switch to other function interfaces; The state variable value that data broadcasting is set again is the resting state value, is convenient to the state of system queries judgment data broadcasting.
In this embodiment, data broadcasting is that data broadcasting self triggers, initiatively carries out from the process that running status enters resting state; And the process of waking data broadcasting up is triggered by external event, and for example, the user has selected the button operation of other functions such as TV, program request.
Need to prove, in Fig. 2 flow chart, in data broadcasting function running, can continue to receive data resource, carry out corresponding judgement and deal with data resource circulation process.
Utilize above-mentioned flow process, when data broadcasting withdrawed from, the main task module of data broadcasting can be preserved current screen, cleans out the current screen menu content then, and no longer handled the data resource that receives.At this moment, data broadcasting is in resting state, and digital TV set-top box can normally be carried out other functions such as TV, broadcasting, program request.And when needs are carried out the data broadcast capability, only need when carrying out this function first, create data broadcasting example, loading respective resources, all need directly from internal memory, to wake data broadcasting up in other cases and get final product, significantly improved the switch speed of data broadcasting.
